fading only slightly or none, moist, oof viscid, silk) or squamulose, 

 equal or tapering below, at (inns compressed, hollow. 



Spores 11-17.5x7-10 p, ellipsoid, smooth, white iii deposit. 



yellowish in Melzer's reagent. Basidia 38-57 • 6-12 //. 1-, 2-, and 1 

 spored. Pleurocystidia 32-57x8-14 /<, clavate, often more or less 

 spathulate, usually with a short stalk, buried; cheilocystidia similar, 



34-50 x 7-11 //. Gill trama parallel to subparallel, hyphae 3-30 p broad. 

 Cuticle a trichodennial turf of septate hyphae, the apical cells of 

 which are undifferentiated. No hypodermium. Pileus trama of radially 

 disposed hyphae. Lactifers present in the trama ol the pileus and 

 lamelhu\ ('lamp connections present on the hyphae ol the cuticle, 

 pileus trama, gill trama, and the snbhvmenhim. 



Habit, Habitat, and Distribution — On soil, in mixed deciduous- 

 coniferous woods, Tennessee, June and July. 



M iter] u. Studied — Tennessee: Hosier L3966, 17671, 22967 (type, 

 from Cades Cove, Great Smoky Mrs. National Park. July 28, 1958). 



Observations — When first observed in the field, this agaric, be- 

 cause of its color and stature, was erroneonslv assumed to be either a 

 form of H. coccineus or an abnormally large //. miniatus. More detailed 

 microscopic study, however, revealed its conspicuous pleurocystidia 

 and cheilocystidia. Its fibrillose-squamulose pileus and large spores 

 indicate a relationship to H. turundus.
